NNS

Possible Resources

Discuss a problem that can be addressed by statistical methods and identify related questions to explore.

Decide which data to collect to answer a question, and the degree of accuracy needed; identify possible sources.

Plan how to collect the data, including sample size; design and use two-way tables for discrete data.

Handling data

(248–273)

Collect data using a suitable method, such as observation, controlled experiment using ICT, or questionnaire.

Handling data

(248–273)

Calculate statistics, including with a calculator; recognise when it is appropriate to use the range, mean, median and mode; construct and use stem-and-leaf diagrams.

Handling data

(248–273)

• Stem and Leaf diagrams

Construct, on paper and using ICT:

- pie charts for categorical data;

- bar charts and frequency diagrams for discrete data;

- simple scatter graphs;

      identify which are most useful in the context of the problem.

Handling data

(248–273)

• Create a pie chart

• Histograms and Frequency Polygons

• Line of best fit

Interpret tables, graphs and diagrams for discrete data and draw inferences that relate to the problem being discussed; relate summarised data to the questions being explored.

Handling data

(248–273)

• Making Comparisons

Communicate orally and on paper the results of a statistical enquiry and the methods used, using ICT as appropriate; justify the choice of what is presented.

Solve more complex problems by breaking them into smaller steps or tasks, choosing and using resources, including ICT.
